[1] The main clinical manifestations are sudden loss of consciousness, inability to touch aortic pulsation, disappearance of auscultatory heart sounds, cessation of spontaneous breathing, or loss of autonomic breathing Organ and tissue organs due to ischemia, hypoxia and failure occurred and eventually died. Cardiac arrest is one of the major causes of adult deaths worldwide, affecting millions of people each year. Timely and effective cardiopulmonary resuscitation is its only treatment, but despite the continuous progress of cardiopulmonary resuscitation, cardiac arrest patients discharged survival rate remains very low, less than 10% of discharged survival in developed countries, China’s only 1.3% ~ ([ 2-3]).
